• SQL Server XML data sources in SSRS 2005

  I have a reports that are trying to read data from a public web service. 1) I couldn't get the report datasource to read the web service (it returns an XML document).

• Visual C# Separating data access form code.

  Greetings All, This inquiry is regarding the separation of data access from a windows forms application. I currently have a class called Data which exposes static methods that basically take in the form variables and then creates, updates and deletes those variables from a sql database. So in my form class I can call this: Int Success = Data.UpdateDate(DateTime date); (return -1 if unsuccessful) My question is – is there a better way to separate the data from the form logic. What are some more popular methods used I often hear the phrase n – tier application - where you would separate out GUI, busin ...Show All

• Visual C# Out of Memory?

  When using my application I seem to get an Out of Memory error at random. I cannot find any common "action" that leads to this. additionally it occurs more frequently when the application is either minimized for more then 5 minutes or is a background window (not the active application) for more then 3-5 minutes. It doesn't happen all the time. I seem to only get it once a week at most. It does not seem to occur when the application is the active window. It's a web browser application and uses the WebBrowser control. it is running on a system with IE6 all latest patches. what's wierd is that I would expect this to occur when the app ...Show All

• SQL Server Excel add-in does not pass filter parameter on drillthrough request

  We used profiler to see what the difference was between the Excel Add-in and the cube browser in Analysis Services 2000.  We created the same reports in both, and the Excel Add-in did not pass the page filter parameter to the stored procedure that processes the drillthrough request.  It works with the Foodmart cube, but the underlying database there is Access, not SQL Server.  I have not been able to find this mentioned as a bug in the product, but it seems more major than the known issue of not being able to drillthrough on the non-default partition.  Has anybody run into this issue ...Show All

• Visual C++ Flicker on custom draw control (ocx) after enabling XP Manifest

  Hello, I've developed an OCX using Visual Studio 6 and MFC; this OCX subclasses the standard Button class and performs custom drawing of its surface and has been working without problems since 1998... If I add the control to a MFC application, developed using VS.NET 2005 with VC++ and MFC, I can see that the control flickers when the mouse rolls over the button surface (internally I call the COleControl::InvalidateControl MFC function) in order to change the surface color: note that I'm using double buffering in order to avoid usual flickers on drawing. If I remove the XP Manifest support, the flicker disappears: how can I exclude my control ...Show All
